Application led May 2, 1924. ,Serial No. 710,480.

The present invention relates to the manufacture of pens and the nibsthereof.

In ens havingnibs provided with smooth ink a( hering or clingingsurfaces the amount of ink adhering or clinging to the nibs 1S,limitedpif the' disadvantage of drops of the ink falling from the nibis 4to be' avoided. Frequently when a pen is resting on its side the inkon the nib will flow to the lower edge of the nib and drop off, the inknot remaining distributed over the ink holding surface of the nib. 1fthe flow of the ink to the nib be too free, the ink -fwill flow to thepoint at a greater rate than demanded by the speed of writing and the'ink will drop from the When the flow is regu-v not readily drop fromthe nib; to provide such nib with preferably a roughened ink' holding onclinging surface, preferably on the inner surface of the body portion ofthe nib whereby a greater quantity of ink may be held upon the nibwithout the dangerv of the same becoming. detached from the nib' andforming blots; tov rovide a pen with such'a nib and a feedp, engagingthe nib whereby the relation of the nib and the feed may. bemaintained;to provide a feed with or without a roughened surface which may engagemore or less intimately with theA inner surface of the nib, whether ornot the latter be roughened; to provide for a novel process of making anib, as by roughening'n the ink holding surface thereof, preferably bysand blasting or the like; toprovide for treating, preferably' byheating, the nib and the feed. for preferably causing the same to.`

intimately lit together, particularly parts 0f the feed fitting with-andinto the/irregular-V ities or inequalities of the roughened surface ofthe nib; to providewhether'or not usin a -roughened nib, for rougheningthe fee if desiredf for aiding in distributing and holding the ink; and,such other andfurther objects, advantages and capabilities as willIlater more 'fully appear'and areL inherently possessed "by theinvention,

Referring to the drawing illustrating the invention, Fi'g. 1 is aview-partly in section' of a pen embodying the invention; Figs. 2 and 3are views of the opposite sides of the nib; and, Fig. 4 is a view in.transverse sec- 60 tion taken on line 1i-'4 of Fig. 1.

Referring now `more particularly to the drawing, Fig. l shows a peuhaving a barrel 1 to an end of which is secured a section 2, preferablyby screw threads 3; The section 65 has an inner extension -1 to which issecured, in 'any suitable manner, anend of the ink sac 5. The section isprovided with a suitable bore in which fits a feed Gand a nib 7, thefeed being provided with an ink flow 7o channel y8 of suitable form. y

The nib 7 .has a writing point 9 and av body portion 10, the innersurface of which is preferabl roughened as'by a sand blast or othersultable means to provide ir1'egu. 75 larities 0r inequalities 11 asclearly shown in Fi 3 of the drawing,

he nib and the" feed are placed together in given relation and insertedin the bore of the section as show n in Fig. 1 of these drawing.'VVhenfit is'desired that the feed fit closely or intimately with the nibso as to prevent relative movement of one with respect to ,the other,the nib and the feed may be treated, as b heating, so that the 86contacting portions o the feed with thenib will setwith'theirregularities' or inequalities of the roughened surface 1l of the nib.

Int will thus be apparent that the two members then will be held closelytogether 'so 9e that the nib will not slide with respect to the feed.Whether or not the nib be roughened, the feed may be roughenedonthesurface engaging with the nib so as toaid in holding and distributingthe ink and the engag 95 xnent of the feed andthe nib may be such as toprovide a. more or less ink holding' space.

wBy roughening the inside surface 11. of the nib'or the feed, or both,a'. greater'qu'antity 100 bf ink may be held without danger of the inkdroppingfrom the nib', or even the feed, and causingblots If the pen berested on its side, the ink will not flow-to thejlower "edge of the niband fall upon the paper'and 105 make blots. The rou hened surface orsurfaces has or have the acultyof distributing, or holding the inkdistributed, over an extensive area.'v Great care in adjusting andmanufacturing the feed is not required since 1x0 or both, moreeiiciently than upon such having a smooth surface or surfaces. In

-this Way a large channel 8 may be used when a rapid flow is required asa result of rapid Writing Without the danger ofthe ink flowing from thepoint upon the paper and forming blotsf i While I have herein describedan embodiment and process of making such pen and nib, it is to beunderstood that the. invention is not limited to the particularconstruction, arrangement of parts and details, or the steps describedand shown, but that it comprehends other constructions, arrangements ofparts detailsand steps Without departing from the spirit thereof.

Having thus described my invention; I claim:

l. 'In a pen, a feed bar and a pen having a roughened inner surface, aportion of said surface being intimately engaged With said bar,I andthat portion of the inner surface of the pen near the nib being smooth.

2. In a pen, a feed b'ar and a pen having a roughened surface, a portionof said surface being intimately engaged with said feed bar..

3. Ima pen, a feed bar, a feed 'channel in said bar, a penA having aroughened surface, a portion of'said, surface being positioned oppositesaid channel, and a portion of said surface being intimately engagedwith said bar. Q

4. In a pen, a feed bar, a feed channel in said bar, a pen having aroughened surface, a portion of said surface being ntimately engagedwith said bar, the inner surface` of said pen adjacent the nib beingsmooth.

5. The method of assembling on a feed bar Ia pen having a roughenedinner surface which consists of heating the feed bar and pressing saidpen against said bartto cause the intimate engagement of said bar Withsaid pen.

, 6. The method of assembling on a feed bar a pen having a roughenedinner surface which consists of softening a surface of said feed bar andpressing said pen against said bar to cause the intimate engagement ofsaid bar with said pen.

In witness whereof', I hereunto subscribe my name to this specification.
